Mini tutorial how I paint one of my dear, wet and scary tyranids.
Carapace (and claws)
Paint using airbrush with mix of Charadon Granite and Black (80/20). Next add Ice Blue to piervious mix (30/70) and highlight carapace. At last add more Ice Blue to mix (80/20), but paint more watered down mixture with lower pressure (about 0,8 atm). Now you have great base for highlights! Use very accurate brush and paint sharp strings using watered down Ice Blue. Next paint again stronger strings with thicker paint and highlight edges of carapace. To finish use Space Wolves Grey using thicker paint to get more visible strings. Carapace is done! Remember to paint carapace with satin varnish to get more realistic look.
Flesh base is also done with airbrush. First layer is mix of Tallarn Flesh and Scorched brown (85/15). Next I highlight with pure Tallarn Flesh. I appiled watered down Ogryn Flesh on most recess areas. After first wash I decided to wash it again, but this time using watered down Brown Ink (Windsor&Newton).
After inking, I rehiglight edges with Tallarn Flesh and next Tallarn Flesh with Bleached Bone (20/80) up to pure Bleached Bone. Finally I add some White to Bleached Bone and I add white light reflections.
Flesh and bloody strings example
First, base layer is Hormagaunt Purple. Next I highlight with Hormagaunt Purple with Bleached Bone (50/50). After this operation I washed whole tongue with Leviathan Purple. I do not care about smothness because it was just only the basic colors that will be covered with blood.
Base is Dheneb Stone, washed with Devalan Mud and highlighted with Bleached Bone. I don’t care about smothness for the same reasons above :)
Blood and bloody strings
Base is primed black and white spray to get horizontal light. I don’t remember all colors that I used…. sorry :/
Shadows: Thornwood Green (P3), Scorched Brown, Battledress Green (P3), Black
